RESEARCH_NOTES:
1. Censuses:
The 1856 Utah Territorial Census was taken because Utah was trying to get statehood to avoid some of the problems that later came. As a result they wanted as many people as possible and frequently included names of everyone in a family without regard to whether they were living or dead. As a result, some of the people listed with the family may not actually have been in the household in 1856. The Adair and Mangums listed included the following heads of households in the Provo and Payson City area: George W. Adair, James Mangum, Joseph Adair (wife Rebecca), Samuel Adair, and Thomas Adair. Source for the following entry is FHL film # 505,913 (index in FHL book 979.2X22u); Ms d 2929 fd. 33, Payson City, p. 8:

2. The following is a small excerpt of a larger listing (see Samuel Newton Adair's notes for full transcription), which was received in digital form from Don and Caroline Smith, 2003. Regardless of the title - "Family Records of Samuel Newton Adair" - I am not sure if this is really a transcript of records kept by Samuel Newton Adair or not. Some death dates given for some of the individuals are after the date Samuel Newton Adair himself died. I spoke in person with Collins Chapman of Mesa, Arizona, in Feb. of 2006. He did not recognize it. Collins' family is the source of most of the biographical information on Samuel and Collin's mother was responsible for the autobiography of Samuel Newton Adair who dictated it to her. The following came to me as an addendum to a typed copy of that autobiography; however, I have now seen a portion of the original handwritten dictation and find no such attachment. The following therefore has no documented source that I can find thus far and should be used with caution:

BIRTH:
1. Per LDS Ordinance Index for temple work done in 1879 by living brothers: "23 Jan 1842 in Pickens Co., Alabama." Family was however in Itawamba Co. by 1839. One Ancestral File entry indicates "Stonsomby, Itawamba, Mississippi".

DEATH:
1. Without mentioning Joseph's name specifically, brother Samuel Newton in his biography does state he lost 3 brothers and his mother in Iowa. The other two brothers were William Jefferson Adair and Ezra Taft Benson Adair both buried at Mt. Pisgah. It appears that Adair family was probably at Mt. Pisgah by the time of this death since William dies within a month afterwards definitely in Mt. Pisgah. Joseph's name does not appear on the monument erected in 1888 but the monument only represents a few of the 100 to 200 who died in the area between 1846 and 1852.
